Troubleshooting and Repair
5.1 INTRODUCTION
This section describes the maintenance, troubleshooting and repair
procedures for the Model 4863 and 2363 Parallel Digital Interfaces. All
comments and errors apply equally to both units unless otherwise stated.
5.2 MAINTENANCE
The 4863 and the 2363 do not require periodic calibration and have no
internal adjustments. However, if the 4863 is used in an application where
the IEEE 488 bus cables are frequently changed or if the input signals
appear erratic, the 4863's connectors may require cleaning to remove wax
and dirt buildup. New GPIB bus and other 'blue ribbon' type connectors are
shipped with a brightener on them. (The brightener is a thin wax like film)
Depending upon cable usage, enough of the brightener may buildup on the
4863's connector to cause intermittent operation.
The brightener is an organic compound and may be cleaned off by washing
the connector with a mild detergent solution followed by an alcohol wash.
Dry thoroughly before reconnecting.
